The digital card is stored in Secure Envionment using Samsung Knox technology to protect yoru payment information. Your physical card details are not stored by Samsung Pay except the last 4 digit of your card number for easy identification.

You will need to setup PIN when you activated Samsung Pay on your Gear. You must enter your PIN each time you put on the Gear, and you won’t need to enter your PIN again until you take your Gear off.
